771,176. Divided and this application September 16, 1949, Serial No.122,812

This invention relates to devices for home and kitchen use althoughcertain features thereof have other uses.

This application is a division of my copending patent application,Serial No. 771,176, filed August 29, 1947.

An object of the invention is a novel and improved juice extractor unit.

Further objects and the entire scope of the iuvention in this divisionalapplication will be further apparent from the following detaileddescription and from the appended claims.

For a better understanding of the invention, reference may be had to theaccompanying drawings forming a part of this application wherein:

Fig. 1 is a fragmentary elevational View partly in sectiondiagrammatically illustrating a powerunit with which this invention canbe used.

Fig. 2 is an elevational view partly in section showing a juiceextractor embodyin the invention;

Fig. 3 is a plan view thereof.

The invention disclosed and claimed in this application relates todevices for extracting juice and the like. This juice extracting deviceis intended for use and in combination with a magnetic power unit of thetype disclosed and claimed in my above mentioned copending application.A brief description of the power device will be set forth in thisapplication to provide the necessary understanding of that device.However, a complete description of the power device may be had withreference to the above mentioned co pending application.

The power device I (Fig. l) comp-rises a suitable casing having, in theparticular embodiment shown, three cylindrical portions or parts 4, 5and 6 which are integrally formed as parts or 2 Claims. (01.146-3)integrally formed at the ends of the main body part I2. The main bodypart I2 of the driving,

magnetic element is fastened to the spindle or shaft I0 in drivingrelation therewith and the upwardly projecting polar parts I3 aredisposed at equal distances from the axis of the spindle or drive shaftI0. This driving magnetic element I I may be of any suitableconstruction.

The driving spindle l0 may be provided at its upper portion andexteriorly thereof with a low pitch thread I5 and the body part I2 ofthe. driving element can 'be provided with an ,open-' ing therethroughhaving a similar low pitch portions of a single casing. The portions 4,5 and 6 are formed of different diameters with the portion 4 having thelarger diameter, the portion 5 a smaller diameter andthe portion 6 ofsmaller diameter than the intermediate portion 5 and these portions areJoined respectively to each other by the flange or shoulder portions 1and 8. The power device I also comprises an electric motor, housed inthe bottom portion of the cas-' part I2 and upwardly projecting polarparts I3 thread I6 formed in the wall of the opening therethrough forcooperation with the low pitch thread I5. In the full line positionshown, the driving magnetic element I I is in the position correspondingto the stationary or de-energized position of the electric motor. In thedash line position, the driving magnetic element II is in operativeposition to drive the food preparing element 2, namely with the endsurfaces of the poles I3 disposed as close thereto as is practicable. Inthis dash line position, the element II is held against further upwardmovement by a nut II fastened to the upper screw threaded end of thespindle I0, and the rotation of the shaft I0 is in a direction to tendto hold the element I I in that position.

In Figs. 2 and 3, I have illustrated one part of a juicing unitembodying the invention which can be used with the previously describedpower unit. This comprises a cylindrical casing having a partition 96disposed approximately one-third of the way up from the bottom andhaving a bottom closure 91 of non-magnetic material such as stainlesssteel. Between the partition 96 and the bottom 91 is housed a magneticdriven element 98. It can have a conical bearing recess on the lowerside thereof and centrally thereof and a ball bearing 99 rests on thebottom 91 and is housed within this recess. A juicer head or reamer I00is suitably journaled centrally of the partition 96 in a journal IOIcarried by the partition 96. The reamer is provided with a stem I00extending down through the journal IOI and having a spline I02 whichengages a corresponding slot or recess in an upwardly projecting centralpart 98' of the magnetic member 98 projecting up intothe central openingformed in the partition 96. The reamer I00 is mechanically coupled withthe driven element 98 by the mere act of inserting the stem of thejuicer head I00 into the bearing IOI with the spline I02 engaging therecess in the driven element. The casing 95 is provided with a drainpipe I03 forthe juice to flow out from the top of the partition 96 and asuitable grate I04 is disposed over the partition 96 so as to catch thepulp of the fruit being juiced. It is only necessary to position thisdevice shown in Figs. 2 and 3 upon a power device such as illustrated inFig. 1, and then energize the motor for driving the juicer head I00.

I claim:

1. A juice extractorunit adapted to removably rest upon the top surfaceof a magnetic driving device of the type havin a rotatable drivingmagnet positioned beneath the said top, the extractor unit comprising anon-magnetic casing having a relatively flat bottom slidable on andofi'the surface of a driving unit, a partition in the casing forming aclosed chamber in the lower portion of the casing, said partition havingone aperture therein forming a journal, a single rotatable element of aferro-magnetic material and having a vertical shaft journalled in saidaperture, said element being disposed in the chamber and adapted to berotated about an axis centrally located with respect to the chamber andsaid aperture, the rotatable element being so positioned to be driven bythe driving magnet of the driving device when the unit is placed on thetop surface of the device, and being constructed to be only magneticallydriven, the portion of the casing above the partition having upwardlyextending walls forming a juice extracting chamber, said juiceextracting chamber having a discharge spout, a reamer, and meansslidably coupling the reamer to said shaft, all the non-rotatable partsbeing of non-magnetic material.

2. A juice extractor unit adapted to removably rest upon the top surfaceof a magnetic driving device of the type having a rotatable drivingmagnet positioned beneath the said top, the ex- 4 tractor unitcomprising a non-magnetic casing having a relatively flat bottomslidable on and oil the surface of a driving unit, a partition in thecasing forming a closed chamber in the lower portion of the casing, saidpartition having one aperture therein forming a journal, a singlerotatable element of a ferro-magnetic material and having a. verticalshaft journalled in said aperture, said element being disposed in thechamber and adapted to be rotated about an axis centrally located withrespect to the chamber and said aperture, the rotatable element being sopositioned to be driven by the driving magnet of the driving device.when the unit is placed on the top surface of the device,.saidrotatable element of .ferro-magnetic material being seated on a bear-.ingon the upper surface of said relatively flat bottom, the portion ofthe casing above the partition having upwardly extending Walls forming ajuice extracting chamber, said juice extracting chamber having adischarge spout, a reamer, and

. meansslidably coupling thereamer to said shaft,

all the non-rotatable parts being of non-magnetic material.
